Call forwarding ip phones in CUCM 8.6 not working.

[CSCO10131057]

Call forwarding from a ip phone (7942) to external number is given a message the phone is no longer in service message. Call forwarding is performed using access code and prefix example 7.1(area code-external number) xxx xxx xxxx.   Tried from both ccmuser and ccmadmin pages any ideas

Hi,

To start with please check if you can dial the call forward destination ( eg 202333444 ) directly from the 7942 IP phone. If yes, then check the call forward css applied on the phone. If these are in place then get a debug from the gateway through which the call is being sent out to see what is going wrong.

Hi. To add a tip to what Manish correctly suggested (+5) verify the css activation policy on call forward section which by default is "with css configured". That means that you have to specify a css next to destination number on call forward all configuration section or you can change the behaviour by selecting other option usig the drop down menu in the above section.

Agree with Carlo (+5).
